Abstract: A developing device has a housing, a developer carrying member, a regulating blade, and a magnetic member. The regulating blade forms a regulating portion regulating the thickness of toner carried on the developer carrying member. The magnetic member is arranged inside the developer carrying member and has a plurality of magnetic poles including a regulating pole arranged at a position where the developer carrying member and the regulating blade are close together. The regulating pole is movable to a first position facing the regulating portion and to a second position rotated to the upstream side from the first position in the rotation direction of the developer carrying member during image formation. The developing device is operable in the developer removing mode in which, when no image is formed, the regulating pole is moved from the first position to the second position and is then returned to the first position.

Abstract: An image forming apparatus includes a conveyance section, an image forming section, a fixing section, a sheet output tray, a toner container, a suitable product determining section, and a control section. The suitable product determining section determines whether the toner container loaded in an apparatus body is a suitable product. When the suitable product determining section determines that the toner container is not a suitable product, the control section allows the conveyance section, the image forming section, and the fixing section to form, on a sheet, a solid image having a circumferential length of one of rotating bodies of the fixing section or longer, and allows the sheet on which the solid image is formed to pass through a fixing nip, to thereby periodically allow a cleaning operation of removing a contamination adhering to surfaces of rotating bodies of the fixing section to be performed.
